The helpdesk module project for Drupal gets new resources
The project is now graced with a page accessible from within Drupal, at: http://drupal.org/node/30947
The page above gives access to the usual developer-oriented features in drupal: issues, CVS, etc.
For further documentation, from requirements to the user manual or the source documentation by phpDocumentor, I've set up a Wiki on http://wiki.audean.com.
An interesting feature of the dokuwiki software used for this new wiki is the presence of an RSS feed on pages, notably on the "recent pages" page. This allows use of an RSS aggregator to track changes to the docs, like the builtin aggregator in the now-free Opera browser.
